The implementation of each helper depends on the architecture, but they are all equivalent to regular I/O functions of similar names. So use regular functions instead and move all helpers into The first patch a simple whitespace cleanup. Until now, contained an include of . As this will go away patches 2 to 4 prepare include statements in the various drivers. Source files that use regular I/O helpers, such as readl(), now include . Source files that use framebuffer I/O helpers, such as fb_readl(), also include . Patch 5 replaces the architecture-based if-else branching in by helpers in . All helpers use Linux' existing I/O functions. Patch 6 harmonizes naming among fbdev and existing I/O functions. The patchset has been built for a variety of platforms, such as x86-64, arm, aarch64, ppc64, parisc, m64k, mips and sparc. v3: * add the new helpers in * support reordering and native byte order (Geert, Arnd) v2: * use Linux I/O helpers (Sam, Arnd) Thomas Zimmermann (6): fbdev/matrox: Remove trailing whitespaces ipu-v3: Include fbdev: Include in various drivers fbdev: Include via fbdev: Move framebuffer I/O helpers into fbdev: Rename fb_mem*() helpers drivers/gpu/ipu-v3/ipu-prv.h | 1 + drivers/video/fbdev/arcfb.c | 1 + drivers/video/fbdev/arkfb.c | 2 + drivers/video/fbdev/aty/atyfb.h | 2 + drivers/video/fbdev/aty/mach64_cursor.c | 4 +- drivers/video/fbdev/chipsfb.c | 3 +- drivers/video/fbdev/cirrusfb.c | 2 + drivers/video/fbdev/core/cfbcopyarea.c | 2 +- drivers/video/fbdev/core/cfbfillrect.c | 1 + drivers/video/fbdev/core/cfbimgblt.c | 1 + drivers/video/fbdev/core/fbmem.c | 4 +- drivers/video/fbdev/core/svgalib.c | 3 +- drivers/video/fbdev/cyber2000fb.c | 2 + drivers/video/fbdev/ep93xx-fb.c | 2 + drivers/video/fbdev/hgafb.c | 3 +- drivers/video/fbdev/hitfb.c | 2 +- drivers/video/fbdev/kyro/fbdev.c | 5 +- drivers/video/fbdev/matrox/matroxfb_accel.c | 8 +- drivers/video/fbdev/matrox/matroxfb_base.h | 6 +- drivers/video/fbdev/pm2fb.c | 3 + drivers/video/fbdev/pm3fb.c | 2 + drivers/video/fbdev/pvr2fb.c | 4 +- drivers/video/fbdev/s3fb.c | 2 + drivers/video/fbdev/sm712fb.c | 2 + drivers/video/fbdev/sstfb.c | 4 +- drivers/video/fbdev/stifb.c | 6 +- drivers/video/fbdev/tdfxfb.c | 5 +- drivers/video/fbdev/tridentfb.c | 2 + drivers/video/fbdev/vga16fb.c | 3 +- drivers/video/fbdev/vt8623fb.c | 2 + drivers/video/fbdev/wmt_ge_rops.c | 2 + include/asm-generic/fb.h | 102 ++++++++++++++++++++ include/linux/fb.h | 53 ---------- 33 files changed, 167 insertions(+), 79 deletions(-)
